Genesis Grill Parts for Weber Genesis 300 Series - 3 Burner

Our review of this Genesis grill parts kit finds it best suited to owners of the Weber Genesis 300 series with front control knobs who need a direct, affordable replacement for worn cooking parts. The kit breathes new life into older E310/E320/E330 models by restoring cooking performance and appearance with a 5-pack of flavorizer bars, two matte enamel cast iron grates and two porcelain-enameled heat deflectors. For anyone troubleshooting uneven heat, rusted bars, or damaged deflectors, this kit replaces the most commonly failing components without changing the grill's original layout.

Key Features

• Direct fit: Compatible with the Genesis 300 series (front control knobs) and specific Weber part numbers, so installation lines up with original mounting points.
• Complete kit: Includes five flavorizer bars, two grates and two heat deflectors, replacing the main cooking surfaces and heat management parts in one purchase.
• Porcelain-enameled steel bars: The upgraded snowflake porcelain finish resists corrosion and restores the grill's appearance while protecting burners.
• Matte cast iron grates: Thick cast iron retains heat for faster searing and improves grill marks and cooking consistency.
• Exact dimensions: Bars and deflectors are sized to match originals, with each flavorizer bar about 17.5in long and each deflector about 13.25in long by 8.75in wide, ensuring predictable coverage.
• Value replacement: Replaces multiple original part numbers so it covers a range of Genesis 300/E3xx variations without buying individual pieces.

Who It's For

This kit is ideal for owners of Weber Genesis E310, E320, E330, S310, S330 and equivalent EP models from roughly 2011-2016 who need to replace corroded flavorizer bars, cracked heat deflectors or worn grates but want to keep their original grill frame. It is especially useful for people who prefer cast iron cooking surfaces for heat retention and searing.

It is not appropriate for Genesis models with side control panels, GS4 Genesis II variants, or the 2022 Genesis 300 redesign; buyers of those grills should look for parts specific to their control layout or generation to ensure proper fit.

Pros & Cons

Pros

• Good fit for many Genesis 300 series models, restoring original function and alignment.
• Durable matte cast iron grates that heat quickly and improve searing performance.
• Porcelain-enameled flavorizer bars and deflectors resist rust and refresh the grill's look.

Cons
